An all-new original novel in which the most powerful hero in the Marvel Universe must free Inhuman slaves imprisoned on a distant world.

WHEN A MYSTERIOUS SPACECRAFT COMES HURTLING TOWARD EARTH, CAROL DANVERS—THE HERO KNOWN AS CAPTAIN MARVEL—NARROWLY PREVENTS IT FROM CRASHING.

The craft’s pilot is Rhi, a young Inhuman woman, part of a group who rejected that society’s caste system and left for the stars in search of a new life. What they found, however, was imprisonment on a planet ruled by a cruel patriarchy. There, Inhumans are treated like currency, and possession of an Inhuman girl brings the master great power and influence. To refuse means death, and Rhi has risked everything to seek help.

Horrified by the picture the young woman paints, Carol pledges to accompany her back to the planet and pulls together a team of heroes to help. Joined by Ant-Man, Mantis, and Amadeus Cho (Brawn), Carol and Rhi set out to free her family, her people, and an entire world.
